Spray-coated contacts from an organic charge transfer complex solution for organic field-effect transistors
We demonstrate the deposition of films of the conducting charge transfer complex TTF-TCNQ from solution by spray-coating. The benefit of spray-coating is the ability to process large volumes of solution, therefore allowing the utilisation of compounds with very low solubility. The sheet resistance i...

| Resumo: | We demonstrate the deposition of films of the conducting charge transfer complex TTF-TCNQ from solution by spray-coating. The benefit of spray-coating is the ability to process large volumes of solution, therefore allowing the utilisation of compounds with very low solubility. The sheet resistance in the TTF-TCNQ film is similar to that of the commonly used organic PEDOT:PSS electrodes, with the added benefit of room temperature deposition and no additional thermal treatments. Spray-coated TTF-TCNQ is used as source and drain electrodes for transistors based on the organic semiconductor C8-BTBT, achieving similar performances in terms of mobility and turn-on voltage than when conventional contacts of MoOx/Au are used, whilst exhibiting a slight improvement in the linearity of the output characteristics. |
